As requested.... along with one other shot of the engine bay:

Nice. Just remember when taking it off not to have the nuts drop down! I'm missing a 13mm deep dish socket somewhere behind my engine! LOL

BTW you're missing the clamp on the brake booster hose....

There's never been a clamp there on my car. It's a barb fitting so is a clamp really necessary? It's made it 70k without a clamp. I'm sure it'll be ok.

[IsaacHayes]

Huh. Mine has a clamp but it's barbed too. No reason for a clamp really, it's not gonna come off. Other car makers don't use clamps and I guess GM did away with it after a while. I just figured they still did!

My 3500 plennum doesn't have threads on the inside of the brake booster port, is it supposed to? I'm going to tap mine regardless.

[IsaacHayes]

FF, Hmm, I know the 3100 plenum is a metal fitting screwed in, and the 3500 is plastic. Other than that I didn't look any closer.

nice that you got the ICM plate to line up with the bolt. Mine wasn't even close.

It still hangs off the back. I had some crappy brackets on there from when I added just the plenum spacers, but I ditched those in favor of the header bolts.

[IsaacHayes]

Ah ok I get it now, so instead of being bolted in the back only, its bolted up top only. I was a bit puzzled.

[whitelightnin04MC]

Yessir

[Rhedalert]

OHHHH!!!! I see!
